Description

Integrated washings processing device and control method thereof
Technical Field
The present invention relates to an integrated laundry treating apparatus and a control method thereof, and more particularly, to an integrated laundry treating apparatus in which a washing machine module for performing a washing process and a dryer module for performing a drying process are disposed in a common cabinet, and a control method thereof.
Background
In general, a washing machine is a device for washing laundry, which is composed of a drum rotatable inside a cabinet and a driving device for rotating the drum. Such washing machines may be classified into top loading (top loading) and front loading (front loading) washing machines according to the posture (post) of the drum.
Unlike a top-in type washing machine having a vertical (upright) drum, a front-in type washing machine has a horizontal drum, and thus laundry is thrown into the washing machine through a front portion of the washing machine. The front-in type washing machine as described above has a smaller size and a greater washing capacity than the top-in type washing machine. In addition, the front-loading type washing machine has high washing performance without causing entanglement of laundry, and thus is widely used.
In addition, a combo type drying-washing machine, in which a drying function is added by installing a drying module in a front type washing machine, is also widely used.
It should be noted that, since there is a limit to the drying capacity of the drying module provided in the combined drying and washing machine, a relatively long drying time is required to dry the whole washed laundry.
Therefore, in order to shorten the drying time, a dryer developed for a special purpose of drying laundry as another laundry treatment device is presented, and particularly, a front-type dryer, which is the same type as a front-type washing machine, is used together with a combination type washing machine.
Such a washing machine and dryer may be installed together in a horizontal direction side by side arrangement, but there is a problem in that an area occupied in the horizontal direction is excessively large.
Therefore, products stacked in a vertical direction by the washing machine and the dryer, particularly products disposed in a manner of stacking the dryer on the washing machine, are sequentially pushed out.
However, as described above, in the arrangement in which the washing machine and the dryer are simply stacked in the vertical direction, separate function modules, particularly, drying modules need to be provided in the washing machine and the dryer, respectively, and thus the stacked products become excessively high in height. As a result, the location where the washing machine and the dryer are installed together is greatly restricted, and for example, when the entire height of the washing machine and the dryer stack is greater than the floor height of a general house, the installation itself becomes impossible.
In connection with this, as a prior art document, chinese laid-open patent publication No. 108950976 discloses an integrated laundry treating apparatus that reduces the size of the entire product, particularly the height of the product, by assembling a washing machine and a dryer in such a manner that they are stacked together inside a single cabinet and sharing a part of components for realizing the function of the product together.
In this prior document, a structure of a driving motor and a shared drying module is disclosed as common parts of a washing machine and a dryer, and particularly, the shared drying module includes a common duct, a condenser, a heater, a fan/motor provided inside the common duct, and inlet and outlet valves for switching an outlet and an inlet of the common duct.
It should be noted that the prior art document only describes that the disclosed common drying module simultaneously supplies hot air to the washing drum and the drying drum and recovers the hot air to simultaneously perform the drying course on the washing machine and the dryer by adjusting the inlet valve and the outlet valve, but does not mention at all means capable of adjusting and controlling the amount of the hot air supplied to the respective washing drum and the drying drum during the simultaneous drying course.
Therefore, even if the drying of the laundry in any one of the washing drum and the drying drum is completed during the simultaneous drying process, the hot wind is continuously supplied to the dried side, and thus there is a problem in that the laundry is damaged by the hot wind or unnecessary power consumption is generated.
Further, since the progress of the drying process of the washing drum and the drying state of the laundry cannot be checked, it is necessary to continuously supply hot air for a preset drying time and drive the drum, which causes a problem of low efficiency in terms of time and power consumption.

To the first outlet 51c of the common drying module 50, one end of a first supply duct 61 for guiding the hot wind discharged from the common duct 51 toward the dryer module 20 side is connected, and to the second outlet 51d of the common drying module 50, one end of a second supply duct 62 for guiding the hot wind discharged from the common duct 51 toward the washing machine module 30 side is connected. That is, as shown, the hot wind passing through the common duct 51 of the common drying module 50 is branched off to the hot wind supply duct including the first supply duct 61 and the second supply duct 62 and is connected to the dryer module 20 and the washing machine module 30, respectively.
The other end of the first supply duct 61 is connected to the dryer module 20, more specifically, to the inflow port 22a of the drying drum 22, and the other end of the second supply duct 62 is connected to the washing machine module 30, more specifically, to the inflow port 33a of the washing tub 33.
One end of a first recovery duct 63 for guiding the hot air exhausted from the dryer module 20 toward the common duct 51 is connected to a first inlet 51a of the common drying module 50, and one end of a second recovery duct 64 for guiding the hot air exhausted from the washing machine module 30 toward the common duct 51 is connected to a second inlet 51b of the common drying module 50. That is, as shown in the drawing, the flow path structure is formed so that the hot air collected in the hot air collection duct including the first collection duct 63 and the second collection duct 64 is converged to the common duct 51.
The other end of the first recovery duct 63 is connected to the discharge port 22b of the drying drum 22, and the other end of the second recovery duct 64 is connected to the discharge port 33b of the washing tub 33.
A heater 53 and a blower fan 54 for generating hot air are disposed inside the common duct 51. Further, a condenser 52 for at least partially removing moisture contained in the hot wind recovered from the dryer module 20 and the washing machine module 30 is disposed upstream of the heater 53 in the traveling direction of the hot wind.
An air supply motor 55 for driving the air supply fan 54 is provided outside the common duct 51 in the vicinity of the air supply fan 54. As shown in the drawing, the driving of the air supply fan 54 may be configured to be received from an additional dedicated air supply motor 55 for driving the air supply fan 54, or may be received from a driving motor of the washing drum 32 or a driving motor of the drying drum 22. Hereinafter, for convenience of explanation, the description will be made with reference to an embodiment in which the blower fan 54 is driven by the blower fan 54 driving dedicated blower motor 55.
As for the detailed structure of the heater 53 and the condenser 52, any means known in the art may be applied. For example, an electric heater 53, a gas heater 53, a heat pump condenser (condenser), or the like can be applied as the heater 53 as the heat generation source, and a water-cooled dehumidification unit, a heat pump evaporator, or the like can be applied as the condenser 52.
The present invention is not limited to this, and for convenience of description, the heater 53 and the condenser 52 implemented by the heat pump module 80 will be described below with reference to these components.
On the other hand, an outlet flow path switching valve V2 for selectively opening or simultaneously opening at least one of the first outlet 51c and the second outlet 51d is provided at an outlet side of the common duct 51, and an inlet flow path switching valve V1 for selectively opening or simultaneously opening at least one of the first inlet 51a and the second inlet 51b is provided at an inlet side of the common duct 51.
As will be described later, the integrated laundry treating device 1 according to an embodiment of the present invention has at least four program modes.
The outlet flow path switching valve V2 functions to switch the outlet flow paths of the common drying module 50 in respective different program modes such that the hot wind is supplied only to at least one of the first outlet 51c and the second outlet 51d of the common duct 51, or the hot wind is simultaneously supplied to the first outlet 51c and the second outlet 51 d.
Likewise, the inlet flow path switching valve V1 functions to switch the inlet flow paths of the common drying module 50 in respective different program modes such that the hot wind is recovered only through at least one of the first inlet 51a and the second inlet 51b of the common duct 51, or the hot wind is recovered through both the first inlet 51a and the second inlet 51 b.
In addition, as will be described later, the outlet flow path switching valve V2 and the inlet flow path switching valve V1 are configured to be able to adjust the opening amounts of the first and second inlets 51a and 51b and the first and second outlets 51c and 51d so as to be able to control the flow rates of hot wind supplied to the dryer module 20 and the washing machine module 30 in a program mode in which hot wind is simultaneously supplied to the dryer module 20 and the washing machine module 30.
On the other hand, the outlet flow path switching valve V2 and the inlet flow path switching valve V1 are connected to valve actuators a1, a2 for driving the valves, respectively, and the valve positions are controlled by the respective valve actuators a1, a 2.
The outlet flow path switching valve V2 and the inlet flow path switching valve V1 have, for example, a three-way valve form. It should be noted that any means capable of switching the three-way (3-way) flow paths and adjusting the opening amounts of the inlet and outlet of the common drying module 50 according to the respective different program modes may be applied to the outlet flow path switching valve V2 and the inlet flow path switching valve V1 and the valve actuators a1 and a2 thereof without limitation, and such modifications will fall within the scope of the present invention.
The detailed description of the control of the valve position in each of the different program modes will be described later with reference to fig. 3 to 6.
Further, the integrated laundry treating apparatus 1 according to an embodiment of the present invention includes: a first humidity sensor SH1 measuring a first humidity of the hot wind recovered through the first inlet 51 a; and a second humidity sensor SH1 measuring a second humidity of the hot wind recovered through the second inlet 51 b.
The first humidity sensor SH1 is intended to measure the humidity of hot air exhausted from the drying drum 22 of the dryer module 20 to confirm the drying progress state of the laundry inside the drying drum 22, and the second humidity sensor SH1 is intended to measure the humidity of hot air exhausted from the washing drum 32 and the washing tub 33 of the washing machine module 30 to confirm the drying progress state of the laundry inside the washing drum 32.
The first humidity sensor SH1 and the second humidity sensor SH1 are electrically connected to the control part 70, and are configured such that a signal regarding the first humidity measured by the first humidity sensor SH1 and a signal regarding the second humidity measured by the second humidity sensor SH1 are periodically transmitted to the control part 70.
Therefore, in the simultaneous drying process of the dryer module 20 and the washing machine module 30, the control part 70 may confirm the drying state of the laundry in the drying drum 22 and the washing drum 32 according to the first humidity and the second humidity. The control part 70 generates a control signal for switching the flow path according to the received first humidity and second humidity and transmits the control signal to the aforementioned respective valve actuators a1, a2, and the actuators a1, a2 drive the valves based on the respective control signals and adjust the opening amounts of the first and second inlets 51a, 51b and the first and second outlets 51c, 51d to supply more hot air to the side where drying is performed less, i.e., the side where hot air having higher humidity is discharged.
The detailed configuration of the opening amount of the first and second inlets 51a and 51b and the opening amount control of the first and second outlets 51c and 51d according to the first and second humidities when the simultaneous drying process is performed will be described later with reference to fig. 8 and 9.
On the other hand, since the first humidity sensor SH1 and the second humidity sensor SH1 aim to check the drying state of the laundry in the drying drum 22 and the laundry in the washing drum 32, respectively, it is necessary to measure the state before the collection flow path from the dryer module 20 and the collection flow path from the washing machine module 30 converge. Therefore, it is preferable that the first and second humidity sensors SH1 and SH1 be provided at positions upstream of the inlet flow path switching valve V1 in the traveling direction of the hot wind, that is, inside the first and second recovery ducts 63 and 64 adjacent to the first and second inlets 51a and 51b, respectively.
Any means known in the art may be applied to the first humidity sensor SH1 and the second humidity sensor SH1 as long as they can measure the relative humidity in the air and convert it into an electrical signal.
Fig. 3 to 6 are schematic configuration diagrams for distinguishing and explaining states of supplying or blocking the supply of the dry hot air to or from the dryer module 20 and the washing machine module 30 in respective different program modes.
As described above, the integrated laundry treating device 1 according to an embodiment of the present invention has at least four program modes, including the first to fourth program modes based on the supply and recovery states of the dry hot wind.
The first program mode is a program for causing the dryer module 20 to separately execute a drying program, and is a program mode for causing the washing machine module 30 to be in a stopped state or to execute a washing program, in which dry hot wind is supplied only to the dryer module 20.
The second program mode is a program for causing the washing machine module 30 to separately execute the drying program, and is a program mode for causing the dryer module 20 to be in a stopped state, in which dry hot wind is supplied only to the washing machine module 30.
The third program mode is a program mode in which the drying module 20 performs the drying program while the washing module 30 performs the washing program, and then performs the drying program, and in which dry hot wind is supplied only to the drying module 20 during the washing program performed by the washing module 30, but when the drying program is performed after the washing program is completed by the washing module 30, the supply and recovery flow paths of the hot wind are switched by the outlet flow path switching valve V2 and the inlet flow path switching valve V1 to simultaneously supply the hot wind to the drying module 20 and the washing module 30.
The fourth program mode is a program mode for causing the dryer module 20 and the washing machine module 30 to simultaneously perform a drying process, and dry hot wind is simultaneously supplied to the dryer module 20 and the washing machine module 30.
First, fig. 3 illustrates a state in which dry hot wind is supplied only to the dryer module 20 in the first and third program modes. Referring to fig. 3, since the laundry machine module 30 is in a stopped state in the first program mode and the laundry machine module 30 is in a state in which the washing program is being executed in the third program mode, the dry hot wind is all supplied only to the dryer module 20, not to the washing machine module 30, and is recovered from the dryer module 20.
The outlet flow path switching valve V2 is driven by the valve actuator a2 to make the first outlets 51c of the common ducts 51 all open and the second outlets 51d of the common ducts 51 all blocked, and the inlet flow path switching valve is driven by the valve actuator a1 to make the first inlets 51a of the common ducts 51 all open and the second inlets 51b of the common ducts 51 all blocked, so that dry hot wind is supplied only to the dryer modules 20 and the dryer modules 20 can individually perform the drying process. Thereby, as shown in fig. 3, a separate hot wind circulation flow path of the dryer module 20 is formed.
Fig. 3 shows an example in which the outlet flow path switching valve V2 and the inlet flow path switching valve V1 corresponding to three-way valves have a butterfly valve (butterfly valve) configuration. Although the present invention is not limited to this, the following description will be made with reference to an embodiment in which the outlet flow path switching valve V2 and the inlet flow path switching valve V1 have a butterfly valve configuration for convenience of description.
On the other hand, in the first and third program modes, the drying state of the laundry inside the drying drum 22 is monitored in real time by the first humidity sensor SH1 during the supply of only the dry hot wind to the dryer module 20 through the common drying module 50.
Therefore, as described later, if it is determined that the first humidity measured by the first humidity sensor SH1 reaches, for example, 60% relative humidity, the control part 70 controls the drying process of the dryer module 20 to be completed, thereby preventing the laundry from being excessively dried and preventing unnecessary power consumption.
Fig. 4 shows a state in which dry hot wind is supplied only to the washing machine module 30 in the second program mode. Referring to fig. 4, since the dryer module 20 is in a stopped state in the second program mode, the dry hot wind is entirely supplied only to the washing machine module 30, and is not supplied to the dryer module 20.
The outlet flow path switching valve V2 is driven by the valve actuator a2 to block all of the first outlets 51c of the common duct 51 and open all of the second outlets 51d of the common duct 51, and the inlet flow path switching valve is driven by the valve actuator a1 to block all of the first inlets 51a of the common duct 51 and open all of the second inlets 51b of the common duct 51, so that dry hot wind is supplied only to the washing machine module 30 and the washing machine module 30 can perform the drying course alone. Thereby, as shown in fig. 4, a separate hot wind circulation flow path of the washing machine module 30 is formed.
In the second program mode, during the supply of only dry hot wind to the washing machine module 30 through the common drying module 50, the drying state of the laundry inside the washing drum 32 is monitored in real time through the second humidity sensor SH1 in the same manner as the first and third program modes described above.
Therefore, as described later, if it is determined that the second humidity measured by the second humidity sensor SH1 reaches, for example, 60% relative humidity, the control part 70 controls the drying process of the washing machine module 30 to be completed, thereby preventing excessive drying of the laundry and preventing unnecessary power consumption.
Fig. 5 illustrates a state in which dry hot wind is simultaneously supplied to the dryer module 20 and the washing machine module 30 in the third and fourth program modes.
Referring to fig. 5, dry hot wind is simultaneously supplied to and simultaneously recovered from the dryer module 20 and the washing machine module 30 to cause the washing machine module 30 to perform a washing process after the washing process is completed in the drying process execution of the dryer module 20 in the third process mode, and to cause both the dryer module 20 and the washing machine module 30 to perform a drying process in the fourth process mode.
The outlet flow path switching valve V2 is driven by the valve actuator a2 to at least partially open the first and second outlets 51c and 51d of the common duct 51, and the inlet flow path valve is driven by the valve actuator a1 to at least partially open the first and second inlets 51a and 51b of the common duct 51, so that dry hot wind is simultaneously supplied to the dryer module 20 and the washing machine module 30 and a drying course can be simultaneously performed. Thereby, as shown in fig. 4, hot air circulation flow paths of the dryer module 20 and the washing machine module 30 are formed, respectively.
As shown in fig. 5, when the simultaneous drying process is performed, the outlet flow path switching valve V2 is controlled such that the first outlet 51c and the second outlet 51d of the common duct 51 have the same opening amount, and the inlet flow path switching valve V1 is controlled such that the first inlet 51a and the second inlet 51b of the common duct 51 have the same opening amount, thereby supplying the drying drum 22 and the washing drum 32 with the same flow rate of dry hot air, respectively, substantially.
It should be noted that the outlet flow path switching valve V2 and the inlet flow path switching valve V1 may be controlled such that the opening amount of the first inlet 51a is not greater than the opening amount of the second inlet 51b and the opening amount of the first outlet 51c is greater than the opening amount of the second outlet 51d, so as to supply more dry hot air to the drying drum 22 and recover it from the drying drum 22 in the case where more dry hot air needs to be supplied to the dryer module 20, for example, in the case where the amount of laundry inside the drying drum 22 is greater than the amount of laundry inside the washing drum 32 and in the case of sterilization and disinfection for the washing drum 32.
On the other hand, in performing the simultaneous drying process, the drying state of the laundry inside the drying drum 22 and the drying state of the laundry inside the washing drum 32 are monitored in real time by the first and second humidity sensors SH1 and SH1, respectively, during the simultaneous supply of the dry hot wind to the dryer module 20 and the washing machine module 30 through the common drying module 50.
As will be described later, if it is determined that at least one of the first humidity and the second humidity measured by the first humidity sensor SH1 and the second humidity sensor SH1 has reached a predetermined relative humidity, for example, the first humidity has reached 60% and the second humidity is less than 60%, the control unit 70 interrupts the drying process of the dryer module 20, and switches the outlet flow path switching valve V2 and the inlet flow path switching valve V1 to the state shown in fig. 4 so that all of the hot dry air is transmitted to the washing machine module 30, thereby preventing the laundry in the drying drum 22 from being excessively dried and preventing unnecessary power consumption.
On the contrary, if it is determined that the second humidity reaches the relative humidity of 60% and the first humidity is less than the relative humidity of 60%, the controller 70 interrupts the drying process of the washing machine module 30, and switches the outlet flow path switching valve V2 and the inlet flow path switching valve V1 to the states of fig. 3 such that all of the hot dry air is delivered to the dryer module 20.
On the other hand, in performing the simultaneous drying process, there may occur a case where the simultaneous drying process as a whole is more delayed than expected due to the first humidity and the second humidity each being less than 60% of the relative humidity or a deviation between the first humidity and the second humidity being serious.
In order to prevent such a delay, the control part 70 calculates a difference between the first humidity and the second humidity, and if it is determined that the respective differences exceed a prescribed critical value, preferably, exceed 10% of the relative humidity, controls to switch the states of the outlet flow path switching valve V2 and the inlet flow path switching valve V1 to supply more hot wind to the side of the dryer module 20 and the washing machine module 30, from which hot wind having higher humidity is discharged.
For example, if it is determined that the first humidity is greater than the second humidity and exceeds the relative humidity by 10%, the control unit 70 controls the outlet flow path switching valve V2 to increase the opening amount of the first outlet 51c of the common duct 51 at a predetermined rate and decrease the opening amount of the second outlet 51d at a predetermined rate, and controls the inlet flow path switching valve V1 to adjust the opening amounts of the first inlet 51a and the second inlet 51b of the common duct 51 at the same predetermined rate.
At this time, it is preferable that the prescribed rate at which the opening amounts of the first and second inlets 51a, 51b and the first and second outlets 51c 51d of the common duct 51 are adjusted be on the order of 5%.
As described above, the amount of opening of the first and second inlets 51a and 51b and the first and second outlets 51c and 51d of the common duct 51 are adjusted based on the deviation between the first humidity and the second humidity and the supplied dry hot wind is differentiated, so that it is possible to minimize power consumption due to the delay of the simultaneous drying process as a whole.
Details regarding the measurement of the first humidity and the second humidity in the progress of the simultaneous drying process described above and details regarding the control of the outlet flow path switching valve V2 and the inlet flow path switching valve V1 will be described later with reference to fig. 9.
Fig. 6 shows an embodiment in which the inlet flow path switching valve V1 and the outlet flow path switching valve V2 are respectively configured of two valves as another embodiment of the integrated laundry treating device 1 of the present invention.
As shown in fig. 6, the inlet flow path switching valve V1 includes: a first inlet flow path switching valve V11 having a dedicated purpose for opening and closing the first inlet 51 a; and a second inlet flow path switching valve V12 having a dedicated purpose for opening and closing the second inlet 51 b.
Further, the outlet flow path switching valve V2 includes: a first outlet flow path switching valve V21 having a dedicated purpose for opening and closing the first outlet 51 c; and a second outlet flow path switching valve V22 having a dedicated purpose for opening and closing the second outlet 51 d.
Unlike the embodiment of fig. 3 to 5, which cannot block the first and second inlets 51a and 51b and cannot block the first and second outlets 51c and 51d at the same time, the embodiment shown in fig. 6 may be configured to block the dryer hot air flow path and the washing machine hot air flow path at the same time.
As described above, by simultaneously blocking the hot wind flow path, lint (lint) and dust generated and accumulated in the condenser 52 during the drying process of the dryer module 20 and the washing machine module 30 can be removed, and the lint and dust remaining when the condenser 52 is washed can be prevented from flowing into the washing drum 32 or the drying drum 22 again and contaminating the washing drum 32 or the drying drum 22.
The first outlet flow-path switching valve V21 and the second outlet flow-path switching valve V22 are driven by dedicated valve actuators V21, V22, respectively, and the first inlet flow-path switching valve V11 and the second inlet flow-path switching valve V12 are driven by dedicated valve actuators V11, V12, respectively.
Fig. 7 is a functional block diagram for explaining the control section 70 of the integrated laundry treating device 1 according to the embodiment of the present invention, and fig. 8 to 9 are flowcharts relating to a control method of the integrated laundry treating device 1 according to the embodiment of the present invention.
Hereinafter, a method of controlling the integrated laundry treating apparatus 1 according to the embodiment of the present invention will be described with reference to the control unit 70 shown in fig. 7.
First, as shown in fig. 8, a program mode selection signal receiving step S1 of receiving a signal for selecting at least one of program modes including at least the first to fourth program modes is performed.
In the program mode selection signal receiving step S1, the control section 70 receives signals for selecting the first to fourth program modes through a selection instruction physically input from the operation section 41 of the control panel 40 of fig. 7. As another aspect, the control section 70 may also receive a signal for selecting any one of the first to fourth program modes by a selection instruction wirelessly input through the communication section CM instead of the control panel 40. The communication section CM may be connected to a user mobile device (not shown) by any wireless communication means known in the art.
Next, the control section 70 executes a program mode determination step S2 of determining which of the first to fourth program modes has been selected based on the received selection signal.
At this time, the control part 70 may provide information that the specific program mode is selected to the user through the display part 42 of fig. 7 or the user mobile device.
If it is determined in the program mode determination step S2 that the first program mode is selected, the control part 70 performs a dryer hot air flow path opening step S3 of opening a dryer hot air flow path as a preparatory step for causing only the dryer module 20 to execute the individual drying program.
In the dryer hot air flow path opening step S3, as in the state shown in fig. 3, the control unit 70 generates a control signal for opening all of the first inlet 51a and the first outlet 51c of the common duct 51 and blocking all of the second inlet 51b and the second outlet 51d of the common duct 51, and transmits the control signal to the valve actuators a1 and a2 of fig. 7.
After the dryer hot air flow path opening step S3 is completed, the control part 70 executes a dryer drying program executing step S4 for executing a drying program to the dryer module 20.
In the dryer drying process performing step S4, the control part 70 may confirm whether the first door 21 of the dryer module 20 is closed through the first door 21 sensor in the sensor part SM shown in fig. 7 before supplying power to the first driving part 91 in the driving part 90 in order to drive the drying drum 22.
If it is confirmed that the first door 21 is in the closed state, the control part 70 supplies power from the power part PM to the first driving part 91 and initially drives the drying drum 22, thereby being able to detect the laundry amount.
The control part 70 compares the detected laundry amount with the required drying time data for each laundry amount previously stored in the memory 71, and transmits expected drying course time information to the display part 42 or the user moving device.
At this time, if the expected drying program time is determined for the initial driving result of the first driving part 91, the control part 70 controls to supply power to the heat pump module 80 and the blower motor 55 of the common drying module 50 and generate dry hot wind.
On the other hand, since the washing machine module 30 is in a state of being stopped in use in the first program mode, the control part 70 controls not to supply power from the power supply part PM to the second driving part 92 of the driving part 90 for driving the washing drum 32.
On the other hand, if it is determined in the program mode determination step S2 that the second program mode is selected, the control unit 70 executes a washing machine hot air flow passage opening step S5 for opening a washing machine hot air flow passage as a preparatory step for causing only the washing machine module 30 to execute the individual drying program, as shown in fig. 8.
In the washing machine hot air flow path opening step S5, as shown in fig. 4, the control unit 70 generates a control signal for opening all of the second inlet 51b and the second outlet 51d of the common duct 51 and blocking all of the first inlet 51a and the first outlet 51c of the common duct 51, and transmits the control signal to the valve actuators a1 and a2 of fig. 7.
After the washing machine hot air flow path opening step S5 is completed, the control part 70 performs a washing machine drying program execution step S6 for executing a drying program for the washing machine module 30.
In the washing machine drying program performing step S6, the control part 70 may confirm whether the second door 31 of the washing machine module 30 is closed through the second door 31 sensor of fig. 7 before supplying power to the second driving part 92 for driving the washing drum 32.
If it is confirmed that the second door 31 is in the closed state, the control part 70 supplies power from the power part PM to the second driving part 92 and initially drives the washing drum 32, thereby being able to detect the laundry amount.
The control part 70 compares the detected laundry amount with the required drying time data for each laundry amount previously stored in the memory 71, and transmits the expected drying course time information to the display part 42 or the user moving device. The expected drying course time of the washing machine module 30 and the drying course time of the above-described dryer module 20 may be different from each other.
At this time, if the expected drying program time is determined for the initial driving result of the second driving part 92, the control part 70 controls to supply power to the heat pump module 80 and the blower motor 55 of the common drying module 50 and generate dry hot wind.
On the other hand, since the dryer module 20 is in the state of being stopped in the second program mode, the control part 70 controls not to supply power from the power supply part PM to the first driving part 91 for driving the drying drum 22.
Fig. 9 shows steps performed to execute the third program mode or the fourth program mode among the first to fourth program modes.
As shown in fig. 9, if it is determined in the program mode determination step S2 that the third program mode is selected, the control part 70 performs a dryer hot air flow path opening step S7 of opening a dryer hot air flow path as a preparatory step for causing only the dryer module 20 to execute the individual drying program.
The dryer hot air flow path opening step S7 is performed substantially the same as the dryer hot air flow path opening step S3 when the aforementioned first program mode is selected, and the control part 70 generates a control signal for opening all of the first inlet 51a and the first outlet 51c of the common duct 51 and blocking all of the second inlet 51b and the second outlet 51d of the common duct 51 and transmits the control signal to the valve actuators a1, a2 of fig. 7 so that the hot air flow path can be generated only for the dryer module 20.
If the dryer hot air flow path opening step S7 is completed, the control part 70 performs a dryer drying/washing machine washing program performing step S8 for performing a drying program with respect to the dryer module 20 and a washing program with respect to the washing machine module 30.
In the dryer drying/washing machine washing process execution step S8, the control part 70 may confirm whether the first and second doors 21 and 31 are closed through the first and second door 21 and 31 sensors of fig. 7 before supplying power to the first and second driving parts 91 and 92.
If it is confirmed that the first and second doors 21 and 31 are in the closed state, the control part 70 supplies power from the power part PM to the first and second driving parts 91 and 92 and initially drives the drying drum 22 and the washing drum 32, thereby being able to detect the laundry amount of the drying drum 22 and the laundry amount of the washing drum 32.
The control part 70 may transmit drying program time information of the dryer module 20, which is expected by comparing the detected amount of dried laundry with the required drying time data for each amount of dried laundry previously stored in the memory 71, and washing program time information of the washing machine module 30, which is expected by comparing the detected amount of washed laundry with the required drying time data for each amount of washed laundry previously stored in the memory 71, to the display part 42 or the user moving apparatus, respectively.
Thereafter, if an expected drying program time of the dryer module 20 is determined for the initial driving result of the first driving part 91, the control part 70 controls to supply power to the heat pump module 80 and the blowing motor 55 of the common drying module 50 and generate dry hot wind.
Next, the control part 70 performs a simultaneous drying process entry or non-entry determination step S9 for determining whether a simultaneous drying process is entered or not by determining whether a washing process of the washing machine module 30 is completed or not and determining whether dry hot wind is supplied to the washing machine module 30 or not.
More specifically, in the drying process of the dryer module 20, it is determined whether or not the washing process of the washing machine module 30 is completed.
If it is determined that the drying process of the dryer module 20 is completed in a state where the washing process of the washing machine module 30 is not completed, the control part 70 ends the drying process of the dryer module 20 and continues the washing process of the washing machine module 30.
In addition, when the washing process of the washing machine module 30 is completed and the drying process of the washing machine module 30 is to be performed after the drying process of the dryer module 20 is completed, the control part 70 controls to perform the washing machine hot air flow path opening step S5 for opening the washing machine hot air flow path shown in fig. 8 and the washing machine drying process performing step S6.
On the other hand, when the washing process of the washing machine module 30 is completed and the drying process of the washing machine module 30 is to be performed in a state in which the drying process of the dryer module 20 is in progress, the control part 70 performs a dryer/washing machine hot air flow path simultaneous opening step S10 of simultaneously opening the dryer hot air flow path and the washing machine hot air flow path as a preparatory step for performing the simultaneous drying process for the dryer module 20 and the washing machine module 30.
In the dryer/washer hot air flow path simultaneous opening step S10, the control part 70 generates a control signal for opening all of the first and second inlets 51a, 51b and the first and second outlets 51c, 51d of the common duct 51 and transmits to the valve actuators a1, a2 of fig. 7 so that the hot air flow paths can be simultaneously generated for the dryer module 20 and the washer module 30.
As shown in fig. 5, the outlet flow path switching valve V2 is driven by the valve actuator a2 to at least partially open the first and second outlets 51c and 51d of the common duct 51, and the inlet flow path valve is driven by the valve actuator a1 to at least partially open the first and second inlets 51a and 51b of the common duct 51, so that dry hot wind is simultaneously supplied to the dryer module 20 and the washing machine module 30 and a drying course can be simultaneously performed.
As previously described, the outlet flow path switching valve V2 is controlled such that the first outlet 51c and the second outlet 51d of the common duct 51 have the same opening amount, and the inlet flow path switching valve V1 is controlled such that the first inlet 51a and the second inlet 51b of the common duct 51 have the same opening amount, thereby supplying the same flow rate of dry hot air to the drying drum 22 and the washing drum 32, respectively, for performing the simultaneous drying process.
On the other hand, as described above, if the simultaneous opening of the dryer/washer hot air flow paths in step S10 is completed, the control part 70 performs a dryer/washer simultaneous drying program for simultaneously performing a drying program for the dryer module 20 and the washer module 30 in step S11.
In the simultaneous drying program performing step S11, the control part 70 performs a humidity measuring step S12 of measuring the relative humidity of the hot wind recovered through the first and second inlets 51a and 51b of the common drying module 50 in real time.
In more detail, in the humidity measuring step S12, the control part 70 performs a first humidity measuring step of measuring a first humidity in real time by the first humidity sensor SH1 to confirm the drying state of the laundry inside the drying drum 22, and performs a second humidity measuring step of measuring a second humidity in real time by the second humidity sensor SH1 to confirm the drying state of the laundry inside the washing drum 32.
At this time, if it is determined that at least one of the first humidity and the second humidity measured by the first humidity sensor SH1 and the second humidity sensor SH1 reaches a predetermined target humidity, for example, the first humidity reaches 60% and the second humidity is less than 60%, the control unit 70 interrupts the drying process of the dryer module 20, and switches the outlet flow path switching valve V2 and the inlet flow path switching valve V1 to the states of fig. 4 such that all of the hot dry air is transmitted to the washing machine module 30, thereby preventing the laundry in the drying drum 22 from being excessively dried and preventing unnecessary power consumption.
On the contrary, if it is determined that the second humidity is 60% and the first humidity is less than 60%, the controller 70 interrupts the drying process of the washing machine module 30 and switches the outlet flow path switching valve V2 and the inlet flow path switching valve V1 to the states of fig. 3 such that all of the hot dry air is delivered to the dryer module 20.
On the other hand, in performing the simultaneous drying process, there may occur a case where the simultaneous drying process as a whole is delayed more than expected due to the first humidity and the second humidity each being less than 60% of the relative humidity or the deviation between the first humidity and the second humidity being severe.
For this, the control part 70 performs a humidity difference value judging step S13 for calculating a difference value between the first humidity and the second humidity and judging whether the corresponding difference value exceeds a prescribed critical value, preferably exceeds the relative humidity by 10%.
If it is determined in the humidity difference determination step S13 that the difference between the first humidity and the second humidity does not exceed the predetermined critical value, the control part 70 controls the dryer/washer simultaneous drying process to be continuously performed until the first humidity and the second humidity reach the target humidity in step S11.
If it is determined in the humidity difference determination step S13 that the difference between the first humidity and the second humidity exceeds the predetermined threshold value, the control unit 70 performs a flow path opening ratio adjustment step S14 for changing the opening amounts of the first outlet 51c and the second outlet 51d of the common duct 51 to adjust the ratio of the hot wind supplied to the dryer module 20 and the washing machine module 30.
In the flow path opening ratio adjusting step S14, the control part 70 controls to switch the states of the outlet flow path switching valve V2 and the inlet flow path switching valve V1 so that more hot wind can be supplied to the side of the dryer module 20 and the washing machine module 30, from which hot wind having higher humidity is discharged.
For example, if it is determined that the first humidity is greater than the second humidity and exceeds the relative humidity by 10%, the control unit 70 controls the outlet flow path switching valve V2 to increase the opening amount of the first outlet 51c of the common duct 51 at a predetermined rate and decrease the opening amount of the second outlet 51d at a predetermined rate, and controls the inlet flow path switching valve V1 to adjust the opening amounts of the first inlet 51a and the second inlet 51b of the common duct 51 at the same predetermined rate.
At this time, it is preferable that the prescribed rate at which the opening amounts of the first and second inlets 51a, 51b and the first and second outlets 51c, 51d of the common duct 51 are adjusted be on the order of 5%.
On the other hand, when the difference between the first humidity and the second humidity has a difference greater than the relative humidity 10% which is a prescribed critical value, for example, a difference of 15% or more, the drum number-of-revolution adjusting step S15 for more increasing the number of revolutions of the drum on the side of the dryer module 20 and the washing machine module 30 from which the hot wind having a higher humidity is discharged may be additionally performed in addition to the flow path opening ratio adjusting step S14.
As described above, the control part 70 continues to perform the dryer/washer-simultaneous drying program performing step S16 in a state where the flow path opening ratio and the drum rotation number are adjusted, and performs the time lapse judging step S17 for judging whether a prescribed time has elapsed after the flow path opening ratio and the drum rotation number are adjusted. The prescribed time may be set to 5 to 10 minutes in consideration of the amount of laundry included in the drying drum 22 and the washing drum 32 and the currently remaining drying course time.
If it is determined in the time elapse judging step 17 that the set predetermined time has elapsed, the control unit 70 performs the humidity measuring step S12 again to complete the drying process based on the humidity measurement result, or performs the humidity difference value judging step S13, the flow path opening ratio adjusting step S14, the drum rotation number adjusting step S15, and the dryer/washer simultaneous drying process performing step S16 again.
On the other hand, as shown in fig. 9, in the program mode decision step S2, when it is decided that the fourth program mode is selected, since it is different only in that the dryer hot air flow path opening step S7, the dryer drying/washing machine washing program execution step S8, the simultaneous drying program entry necessity decision step S9, which are executed in the third program mode, are omitted, and the remaining steps are identically executed, the control part 70 controls to directly cause the dryer module 20 and the washing machine module 30 to execute the simultaneous dryer/washing machine hot air flow path opening step S10, and to execute the aforementioned subsequent steps.
As described above, it is understood that the technical configuration of the present invention described above can be implemented in other specific ways by those skilled in the art to which the present invention pertains without changing the technical idea or essential technical features of the present invention.
Therefore, the above-described embodiments should be understood as being illustrative and not restrictive in all respects, and it should be understood that the scope of the present invention is not presented by the foregoing description but by the appended claims, and the meaning and scope of the appended claims and all changes or modifications derived from the equivalent concept thereof are included in the scope of the present invention.
